UltraHoist Drawworks System UH 3G-750-3000-DDW Cameron’s UltraHoist drawworks deliver efficient hoisting and lowering during drilling, tripping and handling operations. All UltraHoist drawworks are AC and gear-driven. The three-speed version offers operational flexibility, both at high speeds and high loads. TM The UltraHoist 750-3000 is a fully-integrated drawworks system, designed to be able to hoist and lower defined loads and velocities during tripping and drilling modes. The UltraHoist is designed for offshore installation and is centered on maintaining personnel safety and increasing equipment service life and long-term optimal performance through component selection and system design. Main Features • T hree-speed transmissions used between AC motors and fixed speed gearbox provide unique, fast line speed and pull characteristics • L ebus grooved drum for 1-5/8” drill line – complete with kickback rollers and easily removable guards • Easily removable cable anchor • C ontrol system interfaces with the Zone Management System for safe interaction with other drillfloor equipment • C ustom PLC software ensures smooth and natural operation for the driller • B uilt-in, self-diagnostic functions with automatic warning system for service and overhaul of main components • O nboard HPU systems for brakes and lubrications fitted with dual pumps and motors • R emote-operated fast shift mechanism in the gearbox to avoid gear-shift problems and load-dropping • Internal gearboxes use a keyless design to avoid stress configurations Safety Features • F ail-safe braking system comprised of two brake discs, one at each side of the drum, and two calipers with brake pads acting on each disc • B raking capacity of the emergency brakes equal to 200% of maximum line pull • A utomatic brake monitoring system, including brake slip detection, drum creep detection and drum response detection • Two separately fused emergency shutdown circuits • Integrated crown and floor saver provides full control of the various braking systems Technical Specifications SI Imperial (US) 2240 kW 3000 hp 680 tonnes 750 tons 59 k∙N 65 tons 1.74 m/sec 343 ft/min 914 mm x 1445 mm 36” x 56.9” Power rating maximum drawworks duty Maximum hook load on 14 lines Maximum fast line pull Maximum block speed on 14 lines Drum size (diameter x length) API 7K drilling equipment Any third-party approval is available upon request Design Area classification Zone 1, IIB, T3 Scope of Supply Options Drawworks skid Foundation bolts Drum and drum support Sound attenuation housing Dual brake disks and calipers Water-cooled AC motors Single-speed gearbox Lifting spreader bar Dual three-speed planetary transmissions AC drives AC motors Operator’s control panel Blowers for cooling of AC motors HPU for lube oil and gearshift system HPU for brake control system UltraHoist control system includes PLC with software as needed for safe and reliable control and monitoring of all drawworks functions Local control panel (for cut-and-slip operations) Block reset sensors Floor/crown saver sensors User manuals/documentation Drawworks duty - low gear Hook Load and Speed Chart * Calculations based on 14 lines, layer 2 over Lebus bar ** Hook load given is in lb, block speed in m/sec Drawworks duty - mid gear Drawworks duty - high gear Cont. duty - low gear Cont. duty - mid gear Cont. duty - high gear Speed - low gear Speed - mid gear Speed - high gear Hook load (lb) 2,500,000 Block speed (m/sec) 2.5 2,000,000 2.0 1,500,000 1.5 1,000,000 1.0 500,000 0.5 0 0 500 1000 1500 2000 2500 3000 0.0 3500 Motor speed (rpm) 4601 Westway Park Blvd. Houston, TX 77041 USA Tel 1 713 939 2211 Andøyfaret 3 N-4623 Kristiansand S.
